Exciting heist game! There are multiple approaches to entering the mansion, in my playthrough I chose the roof. Taking down the snipers with the tranquilizer gun was fun, at least until the chimney I was climbing collapsed. Not sure if that was scripted or a trap?It brought me right to a garden level where there was a cool chase sequence involving a tiger. After that it was back in the mansion and on to the vault.The patrolling guards' narrative was amusing with a couple of in-jokes, although their AI needs a little work. I crouched right by one and they didn't see me. The game has good weather effects though, which actually distracted them so I could get to the elevator leading down.Some weird dialogue in the elevator made me think I was missing something, but anyway after that it was straight to the vault and the emerald. The game seemed to glitch a little on picking up the emerald but I guess that's why it's free... all in all a good game experience!
